摘要：
FIELD: medicine.SUBSTANCE: invention relates to the field of medicine, namely to traumatology and orthopedics, and is intended for use in the treatment of patients with intra-articular fractures of the humerus in conditions of trauma and orthopedic, surgical and other hospitals. Before performing the surgical treatment using standard radiography, as well as multilayer spiral computed tomography with volumetric image reconstruction, the character and localization of fractures of the proximal humerus are determined. Perform surgery in the patient's position on the back with the abduction of the injured upper limb to the side at an angle of 30–45°. Under the control of the electron-optical converter, two punctures of the skin and subcutaneous fat are performed 7–8 cm below the fracture level using 1.8 mm diameter spokes, one on the lateral surface of the shoulder and the second on the anterolateral surface of the shoulder. At the site of punctures, expansion cuts of 0.8–1.0 cm long are made and a defender of soft tissues is installed. Two perforation holes 5–6 mm in diameter in the cortical layer of the proximal fragment of the humerus with their axes displaced relative to each other by 1–2 cm along the height of the bone are performed perpendicular to the axis of the bone along the guide spokes with a cannulated drill, the axis of the perforations have an angle of 30–45° in relation to each other. Then, after removing the guide pins, a closed manual reposition of the fracture is performed by introducing the pre-fixation spokes with a diameter of 1.8 mm through each perforation hole intramedullary proximally with their movement beyond the fracture line. Then, each previously prepared Y-shaped elastically tight fixation spoke with the formation of elastically flattened ends and with a ring-shaped intersection in the form of ring-shaped ears with a diameter of 7–8 mm, passes alternately through each perforation hole and is intramedullary hammered through the proximal fra
